Does anyone know how to figure out how old they are?
Hi ! Where did you find it? Check the geological map of your area and it will tell you what kind of rock and how old they are (jurassic, cretaceous...). Then check how many millions years this period happened. From your pic this is some kind of limestone that sedimented in the océan. It could be a few million years to hundreds million years !
